Team owner Maury Gallagher told motorsport.com on Saturday the organization would like to make a decision in the next month.

GMS campaigns three full-time Camping World Truck Series programs and two Xfinity Series teams. GMS is the defending Truck Series champion with Johnny Sauter, who currently leads the standings.

"According to (general manager) Mike (Beam), a Cup car can be made from an Xfinity car with a few changes," Gallagher said. "So we're building inventory that - assuming there aren't major changes - can be easily converted. We're just getting to the point where we're getting a good stock of new cars. We've been working with some of last year's stuff - we have an affiliation with JR Motorsports. So we've been using their stuff. Bought some cars, but we're finally using our own stuff. Hendrick Motorsports is supplying the chassis."

Hendrick would also provide the engines and equipment for GMS's Cup effort "assuming they could work with us," said Gallagher.

If Gallagher elects to compete in Cup for the 2018 season, the organization will make a trial run with Spencer [Gallagher] behind the wheel.

Whether GMS would field one or two cars in Cup depends solely on sponsorship. Gallagher is leaning towards one team - if it happens - due to the challenges associated with the move. There's also a charter to consider as well as driver selection. Gallagher has heard rumors about Kasey Kahne potentially driving a Cup car for GMS in 2018. However, Gallagher says he has not personally spoken to the driver.
